BACKGROUND OF THE INVENTION

This invention has to do with a locking cable hanger system for use in the solar, mining, and electrical industries. In solar, mining, and electrical industries there is a need for electrical cables to extend from a power or signal source to a location of application. Such cables are usually supported by a messenger wire that are themselves independently structurally supported and strung along the planned cable route. In solar plants, direct current wires attach first to the solar panels and then run to combiner boxes before extending further to power inverters. In addition, alternating current power cables are used to power the motors that control the trackers, devices that rotate the solar panels to follow the sun in order to obtain maximum power during daylight hours.

Prior to 2014, AC and DC cables could be bundled immediately adjacent to, and touching, one another in a wire management system for the solar panels. In the new National Electric Code of 2014, the AC and DC cables must not be immediately adjacent to one another, but must have a degree of separation from one another. Power carrying cables have a tendency to induce errors or interfere with the signal wires that are located in close proximity to them. This new requirement also applies to other applications outside the solar power industry, such as the mining and electrical industries.

Because of the increased use of trackers in solar power plants, there is increased use of category five cables and other data wiring. This type of control wiring is used to give power plant operators feedback from the solar power plant array on what angles the panels are stationed, and what the proper angle should be to maximize power output from the sun. This data and information is constantly monitored to obtain maximum power output from the thousands of solar panels in the solar power plant. The type of wiring used in collecting data is sensitive to cables used for AC and DC power and because of that sensitivity, data wiring cannot be bundled with power cables and must be supported by a separate carrier that is at least one inch away from all power cables.

In solar power plants, mining and other electrical applications, there are various sized wires and bundles of wires with an almost unlimited variety of wire bundle sizes. Bundle size is becoming very important in the manufacture of hangers to accommodate these various sizes, especially in multiple carrier hangers.

The cable hanger has a unique locking arm attachment section which has a closed loop spiral for a secure lock on the messenger wire. In the past, hangers had open loops or modified open loops on the top attachment section which could easily fall off if the hanger were bumped or hit during the wire loading process. In a solar plant there is a recent move to tracker systems which utilize more wiring than previously fixed in place systems. There is also the new NEC code which went into effect Jan. 1, 2014, which states that all AC and DC wiring must now be separated in any hanging or support system. Because of these changes, the wire management systems are much more complex, especially given the vast number of wires involved in a utility scale solar power plant. With these changes, the hangers are initially installed on the messenger wire with a captive top spiral loop, and the bundles of cables are loaded separately in the carrier or carriers of the hanger. This process continues until all individual cables and bundles of cables are supported in the hangers. In the process of loading cables, the hangers are constantly bumped and jostled as they are loaded with bundles of cables. All styles of hangers presently on the market can easily fall off the messenger wire because they are only hanging by one open loop, and they can fall off when bumped during cable installation. Cambria County's Association for The Blind And Handicapped (“CAB”) is a new and improved captive locking arm designed to securely grip the messenger wire so the cable hangers stay in position during the entire loading process and will not fall off when bumped or knocked. After all cables are loaded, the other top attachment end of the cable hanger is then squeezed and locked on the messenger wire.

The new NEC code requires any cable support system to have supports that are spaced at no greater than twelve-inch intervals. This applies to cable trays, hangers or all other types of cable support systems. The old-style hangers with their open style loops can fall off easily during installation and also easily slide out of their twelve-inch spacing when loading the cables. This is a more serious problem when you consider that there are tens of thousands of hangers being installed in the desert heat which can reach 120 degree F. Any wasted labor is a high additional cost in this environment. The new unique captive closed loop locking arm on CAB's cable hangers securely retains the hanger in place even when bumped or knocked around during the cable installation process. This improved captive engagement will also keep cable hangers securely in position on the twelve-inch centers and eliminate the need to reposition hangers on twelve-inch centers after all cables have been loaded into the carriers of the hangers.

A major factor affecting labor costs during installation of cables is how easily the electrician can load the cables and bundles of cables in the hangers in the stifling heat of the desert where solar power plants are usually located. All styles of cable hangers presently on the market will easily swing from side to side as they are initially suspended on the messenger wire. This means an electrician must take one hand and properly align the hanger in a 90 degree perpendicular orientation to the messenger wire in order to load the cables or bundles of cables in the hanger with the other hand. This two handed process of aligning the hanger increases the time necessary to load cables over the thousands of feet of messenger wire with the hangers on twelve-inch centers. The newly designed captive top locking arm of the CAB cable hanger addresses this problem by always maintaining the hanger at a 90 degree orientation to the messenger wire on initial installation. The newly designed top locking arm totally eliminates any lengthwise swinging or traveling movement from side to side and allows the electrician to use both hands for the loading of cables and cable bundles. The new design feature will save many hours of labor in the field and improve efficiency by maintaining twelve-inch centers on the messenger wire when installing all types of cables or cable bundles.

The secure gripping top locking arm is a major improvement in hangers which can save hundreds of hours of labor on a large scale solar power plant; it greatly improves the efficiency of electricians and the quality of cable installations. Three major advantages of the new secure top locking installation arm are: the elimination of hangers falling off the messenger wires during loading, maintaining hangers at the proper orientation to the messenger wire for ease of cable loading, and maintaining the cable hanger on the messenger wire at the specified spacing for improved quality and speed of installation

BRIEF SUMMARY OF THE INVENTION

This invention has to do with a locking cable hanger and multiple cable carriers or saddles on one hanger.

The arrangement according to the present invention comprises a flexible wire of shape retention material formed so as to have an elongated u-shaped configuration forming a pair of spaced apart side arms extending from a closed configuration on one end to an open configuration on the other end. Cable supports (saddles) extend across the space between the side arms with co-operating elements of support and attachment between the cable supports and the side arms to support the cable supports on the wire hanger between the side arms. Attachment sections are formed on each of the open ends of the spaced apart arms with the attachment sections being elastically shape resilient and flexible so as to be bent together for attachment to a messenger wire. The attachment sections comprise two loops, one of which wraps around the messenger wire to effectively lock it in place and the other an open loop which simply latches onto the messenger wire. Installation involves twisting the locking arm around the messenger wire to secured it in place, then squeezing the cable hanger from both sides to a point when the second loop goes past and under the messenger wire so when it is raised and released, the second loop forcefully engages the messenger wire.

This locking hanger and saddle system can have one to five individual separate saddles or cable supports arranged in either a vertical or horizontal configuration. The saddles can attach to the cable hanger in a variety of positions to provide a greater support area for cables and to allow for the separation of cable bundles. One cable hanger can include one to five saddles to accommodate up to five cables or bundles of cable separately. In the vertical design, the saddle can lay on the bottom of the ring or through a wire form retention designed to be attached anywhere from the bottom of the ring to the top of the ring. In this manner of construction, the spacing distance between the saddles can vary to any size to accommodate any size cable or cable bundle. In the horizontal design the saddle would lay on the bottom of the hanger for additional cable support.

The locking saddle and hanger assembly according to the present invention also includes the option of an integrated closed loop on the top of the hanger which is used to safely hold category five cables or other small wiring in an area separate and has a good distance from the bundles of power cables. In this manner of construction, the more sensitive fiber-optic or control wires are retained in a separate carrier at least one-inch from the bundles of power cables in the horizontal or vertical design of this cable ring in saddle arrangement. The distance of separation will ensure there is no signal strength loss or interference on the category five cables from the power cables.

The saddle and hanger system according to the present invention also includes the option of a total or partial coating of PVC, plastisol, or other style coating on the saddle and hanger assembly. The PVC coating is a high dielectric grade and flame retardant. The coating has UV inhibitors for the more demanding environments of solar power plants in desert locations and for improved performance and highly corrosive environments. The total PVC coating on the cable hanger assembly provides additional corrosion resistance and protection of cables; it also add stability by providing a more secure grip of the top attachment loops to the messenger wire. A totally PVC coated single or multiple cable ring and saddle assembly is also easier to handle and install with a heavy 50 to 100 mil inch thick PVC coating over the entire surface. This coating helps to retain all saddles in a fixed position which eliminates the chance of loose saddles moving out of position during installation. The PVC coating is 50 to 100 mils inch thick which also has the added benefit of providing cushioning for the hands when squeezing in installing the cable hanger on the messenger wire. This benefit improves efficiency by allowing more cable hangers to be installed and significantly reduces the fatigue factor of the hand.

Materials used for the cable hangers include high tensile spring steel such as class 50 galvanized steel, copper clad steel, or type 316 stainless steel. Material can be 0.125 to 0.250 inch diameter high tensile spring steel, round or rolled flat wire form. This high quality material provides maximum strength with a smooth, flat surface for the support of cables and rounded edges for the protection of cable jackets.

The hanger 10 is formed of a wire 14 that has opposing ends 11 and 13 that has been bent into a U-shaped configuration to form at least one (one to sometimes five) cable carrier formations 16, 17 with a cable carrier divider 18 separating cable carrier formations 16 and 17. The hanger 10 has shoulders 20 and 22 that extend towards each other from the lateral opposing sides 30 and 32 of the hanger 10. Formed on the distal end of shoulder 22 is the spiral gripper 24 that engages the messenger wire 12. Formed on the distal end of shoulder 20 is the locking hook 26 that has the data carrier loop 28 formed on its distal end. The cable carrier formations 16, 17 are of the same or different widths so that different cable sizes may be loaded onto the hanger 10 prior to it being locked in place. A similar hanger 10 is shown further down the messenger wire 12 to show how the cable may be loaded into several hangers prior to the top locking loop 26 being engaged with the messenger wire 12. The wire 14 used for the hanger 10 is selected from the group consisting of round or flat rolled galvanized or stainless steel spring material. The wire 14 will have a shape memory retention property so as to provide a locking force when both the spiral gripper 24 and the locking hook 26 are engaged with the messenger wire 12. In order to fully engage the hanger 10 with the messenger wire 12 lateral sides 30 and 32 must be squeezed so that shoulders 20 and 22 come towards each other and the locking hook 26 comes under the messenger wire 12 so that when the squeezing of the hanger 10 is released the locking hook 26 will engage the messenger wire as is more formally shown in FIG. 2 .
